Alright, I've finally had the time to "screen print" another shirt, and this time I've made a tutorial for all you out there....
Materials needed: a t-shirt, yucky/cheap paint brushes, an embroidery hoop, screen printing ink (I use Speedball brand), a glue that isn't water-soluble (I use Modge Podge), curtain sheer material/tulle/old nylons, and a computer with a printer (or a good hand for drawing things).
Find an image you like and that has good contrast. My cow needed to be "cut out," and I've only got Microsoft Paint on this computer and it worked fine.
Save the image as a Monochrome Bitmap...
